title: Rapid and accurate chromatic dispersion measurement of fiber using asymmetric Sagnac interferometer.
abstract: We propose and experimentally demonstrate an advanced method for chromatic dispersion measurement of fiber. This technique is based on spectral interferometry by using an asymmetric Sagnac loop and broadband optical source. The chromatic dispersion can be directly obtained from the spectral interferogram seen from an optical spectral analyzer. This method is rapid (<1 s), accurate, simple, low cost, and can provide a large dispersion measurement range.
